I have two clients that I have set up the TSU9200 for. the RFX9200 locks up and then you get the command failed issue.

I have told these clients to unplug the RFX9200 when this happens and that fixes the issues for a few months.

Maybe the RFX9200 needs to be plugged into a UPS or a really good surge protector. I really don't know if that will fix it for good.

But right now the "Command Failed" error is because of the RFX9200 and not the TSU9200.
